I've read a book on the series of attempt on Tirpitz's life and there's a chapter on the attack of the x-crafts. Three midget subs, or x-crafts, were sent. One was lost. Two managed to lay charges under the Tirpitz before their crew, a total of six, were captured. Their captors noted their fidgetness. They were especially anxious to get as far away from the ship as possible. The Germans had a thorough search of the ship but found nothing. When the bombs finally went off and heavily damaged the Tirpitz, the crew cannot help but let out cries of joy, much to their captor's dismay, no doubt. They were treated well by the Germans. Two VC won.
Good stuff for comedy, I'd say.
